Our product needs SMS, so it has to be 3rd party SIM. FW 0.6.1.
The application is up to 12 hours online operation ready for a button press, followed by publishing a temperature value, RSSI to a network connected screen in the room. This button press may happen a couple of time a day, up to every 15 seconds for long periods.
Unfortunately available 3rd party SIM+APN does not come with long UDP timeouts. UDP timeouts are around 30-60 seconds. TCP timeouts are about 1800 seconds - so up to 60 times longer. Keep-alive data adds up with UDP at 122 bytes per update.
Being new to the platform, I wonder if the following is all that is needed to change between TCP and UDP protocol, and what experience have others had with frequent UDP keep-alive vs TCP overhead and stability on Electron?
